COVER-OVER-LAP GAUGE.

Application led August 17, 1923.

To all whom t may concern:

Be it known that I, VAN DEWEY HrGBn-n, a citizen of the United States, residing at Lewiston, county of Androscoggin, State of Maine, have invented certain new and useful Improvements in CovenOverlap Gauges, of which the following is a specification.

rIhis invention relates to a method of and apparatus for gauging the extent which the cover overlaps the leaves of a pamphlet or the like preliminarily to stitching together the cover and leaves in a wire stitching machine of the usual type.

The object of my invention is to provide a simple and accurate method of and apparatus for mechanically gauging such overlap whereby to eliminate the potential chance for serious error which exists under present practice.

For the purposes of this application I shall show and discuss my invention in its adaptation to a wire stitching machine of the saddle back type, although it will be understood that such treatment is purely illustrative and in no way limiting.

The method of practicing my invent-ion, together with convenient and satisfactory apparatus for carrying out the principles involved, is described and illustra-ted in the accompanying specification and drawings, and the characteristic features of novelty are particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is an elevation of a wire stitching machine of the saddle back type equipped with a gauge in accordance with my invention.

Figs. 2 and 3 are face and edge views, respectively, of such gauge removed.

Fig. 4 is a detail view particularly illustrating the method of gauging with my device, and

Fig. 5 is a section on the line 5 5 of Fig. 2.

I have indicated at 1 the saddle back work table of a wire stitching machine of the saddle back type over which a pamphlet consisting of a plurality of leaves L and an overlapping cover C, is laid as shown in Fig. 4, for stitching by the stitching instrumentalities of the machine.

My gauge consists of a leaf gauging plate 2, one of the longitudinal margins 8 of which constitutes a gauging edge against Serial No. 657,987.

which the adjacent margins of the leaves L I plate 2 has xed therein upstanding thread- P ed studs 7 which project through said slots 6. Mounted on said studs are clamping nuts 7 adapted to be set tightly against the plate 4 to hold the adjustment thereof. By adjusting the plate 4 laterally over the plate 2, the gauging edge 5 may thus be set at various positions relative to the stationary gauging edge 3, according to the desired extent of overlap for the particular pamphlet being stitched.

The gauge in its entirety may be mounted upon the saddle back 1 of the machine as shown in Figs. 1 and 4 in any suitable manner, as by bending the plate 2 upon itself at its lower end, as indicated at 8, to prot vide an upturned clamping head 9 spaced from the main body portion of the plate 2 and receiving the lower edge of one of the wings forming the saddle back 1. The gauge is clamped to said wing in any suitable manner. as by the set screws 10.

As shown in these drawings, however, a strengthening piece 11 is sweated to the lower end of the plate 2 and is itself upturned to provide the clamping head. the plate 2 not being bent. The right hand edge of this strengthening piece 11 is inset from the leaf gauging edge 3 a distance corresponding to the maximum distance which the slots 6 permit the cover gauging edge 5 to be inset from said edge 3.

Although I have shown and described lla' sortedto Without departing from the spirit of my invention if Within the limits'of the appended claims.

That l therefore claim and desire to secure by Letters Patent is:

l. An overlap gauge for determining' the extent Which the cover overlaps the leaves of a pamphlet preliminarily to stitching together the cover and leaves in a stitching machine, comprising a relatively stationary flat leaf gauge adapted to be mounted upon the Work support of the stitching machine and having a continuous straight edge against which the adjacent marginal edges of the leaves are adapted to be abutterh and a llat superposed cover gauge mounted upon said leaf gauge for adjustn'ient laterally thereof and having an upstanding cover gauging projection adapted to be inset from the gauging edge of said leaf gauge and against Which the adjacent marginal edge of the cover is adapted to be abutted.

2. An overlap gauge for determining the Y extent Which the cover overlaps the leaves of fill a. pamphlet preliminarily to stitching' together the cover and leaves in a stitching machine` comprising a relatively stationary flat leaf gauge plate adaptedto be mounted upon the Work support of the stitching maf chine and having a longitudinally extending leaf gaugingv straight edge disposed transversely of said Work support and against Which the adjacent marginal edges of the leaves are adapted to be abutt-ed, and a flat superposed cover gauging yplate mounted upon said leaf gauging plate for adjustment laterally thereof and having an upstanding cover gauging edge adapted to be inset from said leaf gauging edge and adjacent which the adjacent marginal edge of the cover is adapted to he abutted.

-3. An overlap gauge for determining the extentvxhich the cover overlaps the leaves of a pamphlet preliminarily to stitching together the cover and leaves in a stitching machine, comprising a relatively stationary flat leaf gauge plate adapted to be mounted upon the Work support of the stitching machine and having a. longitudinally extending leaf gauging straight edge disposed transversely of said Work support and against Which the adjacent marginal edges of the leaves are adapted tol be abutted, a flat superposed cover gauging plate mounted upon said leaf gauging plate for adjustment laterally thereof and having an upstanding cover gauging edge adapted to be inset from said leaf gauging edge andV against Which the adjacent marginal edge ofthe cover is adapted to be abutted, said cover gauging plate having a laterally extending slot,.a

threaded stud extending from said leaf gauging plate through said slot, and a clamping nut adjustable on said stud against said cover gauging plate for holding the adjustment of said plates relative to each other.

il. An overlap gauge for determining the extent Which the cover overlaps the leaves of a pamphlet preliminarily to stitching together the cover and leaves in a stitching machine, comprising a relatively stationary leaf gauge plate having one end bent upon its-elf yand upturned to receive one edge of the Work support of the stitching machine, means for releasably clamping said upturned edge to said Work support, said plate having a longitudinally extending leaf gang ing edge disposed transversely of said Work support and against Which the adjacent marginal edges of the leaves are adapted to be abutted, and a cover gauging plate mountedupon said leaf gauging plate for adjustment laterally thereof and having an upstanding cover gauging edge adapted to be inset from said leaf gauging edge and against Which the adjacent marginal edge of the cover is adapted to be abutted.

5. An overlap gauge for determining the extent Which the cover overlaps the leaves of apamphlet preliininarily tostitching together the cover and leaves in a stitching machine, comprising a relatively stationary leaf gauge plate having one end bent upon itself and upturned to receive one edgey of the Work support of the stitching machine, means for releasably clamping said upturned edge to said Work support, said plate having a longitudinally extending leaf gauging edge disposed transversely of said Worlr support4 and against Which the adjacent marginal edges of the Yleaves are adapted to be abutted, a cover gauging plate mounted upon said leaf gauging plate for adjustment laterally thereof and having an upstanding cover gauging edge adapted to be inset from said leaf gauging edge and against Which theA adjacent marginal edge of the cover'is adapted to be abutted, said cover gauging plate having a laterally ext-ending slot, a threaded-stud extending from sai leaf gaugingplate through saicl7 slot, and 'a clamping nut adjustable on said stud against said cover gauging plate for holding the adjustment of said plates relative to each other.

In testimony whereof I aflix my signature in presence of tWo Witnesses.
